The italicized sentence in the excerpt is discussing the reliability of skinfold measurements. Reliability is a measurement concept that refers to how consistent and accurate the results of a measurement tool are over time and across different testers. The sentence notes that reliability coefficients are slightly lower with novice testers, indicating that there may be some variability in results when less experienced testers are conducting the measurements. This is an issue of objectivity, which refers to the consistency and accuracy of measurements across different testers. Therefore, the best choice is E, objectivity.
